Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
KVM: x86: wean fast IN from emulator_pio_in<br />
<br />
Use __emulator_pio_in() directly for fast PIO instead of bouncing through<br />
emulator_pio_in() now that __emulator_pio_in() fills "val" when handling<br />
in-kernel PIO. vcpu->arch.pio.count is guaranteed to be &#39;0&#39;, so this a<br />
pure nop.<br />
<br />
emulator_pio_in_emulated is now the last caller of emulator_pio_in.<br />
<br />
No functional change intended.
